After yesterday's sync I found mythtv's overlay not able to build anymore due to missing dependency: media-tv/linuxtv-dvb-headers is no longer present in the tree. A quick search shows that it has now become virtual/linuxtv-dvb-headers [1].
I suppose that my only options for rebuilding mythtv are to wait for upstream to update the ebuild or to update it myself. How difficult would the latter be? raf [1] https://bugs.gentoo.org/show_bug.cgi?id=403929
